MACHINE FOR COVERING WIRE.

SPECIFICATION forming ea of Letters Patent No. 463,389, dated November 17, 1891. Application filed November 3, 1890. Serial No. 370,188. (No model.)

To all whom, it may concern:

Be it known that I, MATTHEW D. LIDDELL, of New Haven, in the county of New Haven and State of Connecticut, have invented anew Improvement in Machines for Covering ire; and I do hereby declare the following, when taken in connection with accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents a front elevation of the machine, the winding apparatus at the right being shown in vertical section. I

This invention relates to an improvement in apparatus for covering Wire for electrical and similar purposes, in which the'covering isin the form of thread wound spirally around the wire, the object of the invention being the construction of a machine in which two runs of wire may-be wound at the same time and the machine adapted to be driven directly from a dynamo arranged upon the machine as substantially a part of the machine itself; and the invention consists in the construction, as hereinafter described, and particularly recited in the claim.

A represents the bed of the machine, which is supported upon suitable legs B B.

C represents a dynamo arranged centrally upon the bed, the axis D being longitudinal. In connection with the axis 1.) is an arbor E at one side and a like arbor E upon the opposite side, supported in bearings Gin the frame H, the said arbors being in line with and so as to' revolve with the arbor or shaft of the dynamo. On each of the arbors E E a flier is arranged, which consists of one side I at right angles to the arbor, two sides J J, extending longitudinally therefrom and connected at their opposite ends by a side K, as clearlyshown. Midway in the length of the flier is a cross-bar L,which forms a division in the flier. The arbor E stops short of this bar L, and upon it a yoke M is hung loosely, and so that by its own gravityit will rest upon the arbor, hanging down within the flier, as clearly shown; On the arbor within this yoke M the wire-spool N is loosely arranged, so that itwill not revolve withthe arbor, and it is prevented from such possible revolution by means of suitable friction between the yoke and the spool, it may be as by frictional, springs O. The yoke is tubular, and into the yoke is an opening P below the wire-spool, into which the wire may be introduced,'and thence,running through the tube forward and upward, will pass out through an opening Q in the yoke in line with the axisof revolution.

Between the cross-bar L and the side K a tubular arbor R is arranged in axial and lougitudinal line with the arbor E. This arbor R opens through the cross-bar L directly in line with the opening Q of the yoke, and also opens through the other side K of the yoke. The side K of the yoke is made removable (here represented as secured to the other part by screWsS) and so that when removed it will expose the end of the arbor R, and when so removed the thread-spool T is placed upon the arbor, then the side K replaced. Thread from the spool is run through guides U, leading radially to the center and upon the outside of the side K of the yoke. The wire com-- ing from the spool T, as before described, passes through the arbor R, and the thread led from the spool T is made fast to the wire. Both the wire-spool and the thread-spool are loose upon their arbors, so as not to partake of the revolution of the arbors, but so as to revolve accordingly as the thread or wire is drawn from them. The yoke M, as repre sented at the right in the figure, is held upon the arbor by a male center 2, formed upon theinside of the forward part of the yoke, fitting into a corresponding female center in the outer end of the arbor. The other end of the yoke is provided with a set-screw 3, which fits into a corresponding annular groove 4. in the arbor, thus securing the yoke upon the arbor, but so as to leave it free to hang vertically by its own gravity while the arbor revolves. Because the yoke Mremains stationary, the wire cannot revolve. As the arbor of the dynamo revolves the flier revolves with it and causes the thread to be wound around the wire, and as the wire is drawn forward from the spool the thread is wound thereon, the movement of the wire corresponding to the convolutions of the thread thus laid upon it.

Outside the flier a tubular guide W is preferably arranged, through which the wire will run, and the winding is produced between this guide and the forward end of the flicr.

Tension is applied to the thread-spool, (here represented as by springs V, arranged to frictionally bear upon the spool,) so that the desirable tension may be given to the thread in laying it upon the wire.

The wire is drawn from the spool N as fast as the covering is applied, and to mechanically produce this run of the wire a spool a is arranged upon a shaft 12 on the frame, to which rotation is communicated from the main arbor through a longitudinal shaft (1, arranged in the machine, driven from a pulley e on the arbor, the shaft, by a worm f, communicating rotation to a gear 9 on a shaft h, and on which shaft there is a pulley i, from which a belt Z runs to a corresponding pulley on the shaft b. The run of wire is connected with this spool, and so that the revolution of the spool will produce constant and steady draft upon the wire. A like arrangement of flier, spools, and arbor is made at both ends of the machine, as shown, so that both may be operated from a single shaft.

It will be understood that the electric current is connected to the dynamo in the usual manner for connecting dynamos with such a current, the power of the dynamo being adapted to the work which is to be performed.

By the machine thus constructed, and with the winding apparatus applied to the opposite end of the dynamo-shaft, a very simple winding-machine is produced, one easily attended and capable of producing a great amount of work.

I claim In a machine for covering wire, the combination of a flier arranged upon and so as to revolve with an arbor, the said revolving arbor extending into one side of the flier, a second tubular arbor in the flier in line with the said first arbor, but so as to leave a space be tween the ends of the two arbors, a gravityyoke arranged loosely upon said first revolving arbor, the tubular yoke having an opening into it below the arbor and an opening from it in line with the opening into the said second tubular arbor, a spool arranged loosely upon said first-mentioned arbor and within said yoke and so that wire therefrom may be led through said yoke and thence through said tubular arbor, a spool loosely arranged 011 said second tubular arbor, and guides on the flier to lead the thread from the spool to the wire, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
